✦ Synopsis

Abatraet-A model is presented which describes the relationship of plane strain fracture toughness (K,,) and yield strength of particle-reinforced metal matrix composites. Tensile tests and fracture toughness tests were conducted on five aluminum 2014-T6 metal matrix composites reinforced with 10 and 15 volume percent of B,C, A&O,, and Sic particles of different sizes. Experimental results showed that larger reinforcement particles enhance fracture toughness. A model was established by proposing that the plastic zone at the tip of particle cracks is of the order of the inter-particle spacing. This model predicted the exact trend from the experimental results.
